Hello, your situation sounds tricky. After restarting your PC and keeping only the power cables for the motherboard and CPU, the relay clicks when you press the power button. You attempted to short it with a screwdriver, but the motherboard light stays on, showing some power is being supplied. The ASUS RGB logo is illuminated and changing colors, suggesting the board is receiving power. Could the power supply unit or the motherboard itself still be inactive despite this indication? Since you don’t have another PSU to test, you might want to check a local store for a compatible one. I’m not sure what to do next.
My initial thought is the power supply unit—likely failed, only providing minimal output for the LEDs. Do you have a PSU tester? It resembles this design: If unavailable, you can use a paper clip or any flexible metal to perform a self-test. Be sure to follow correct procedures to avoid shocks. If that doesn’t resolve it, your motherboard could be damaged. You might also consider testing another PSU together. For convenience, you could bring your system to Microcenter during low-demand hours and request a quick check.
If testing the power supply with that short circuit loop, you will need a DVM to check the voltages. Surprisingly, some people today do not have a DVM (digital multimeter). How common? One in my tool kit, one on the workbench, one out in the van. I do have my mother's ones somewhere though they are analogue and date back about 40 years and she'd had hers for years too. They do work.
